The 2011 survey of Illinois farmers concerning farmer reactions to restrictions on fall application of nitrogen was conducted in the summer of 2011. The survey was mailed to 1,162 farm operators in Dekalb, LaSalle and McLean counties. These were farm operators with more than 100 acres who were listed as Federal farm program participants. The farm operator address database was based on 2009 information and was provided to the project by 1st Farm Credit Services who acquired it from Farm Market iD. a Telematch, Inc. company. Ryan Voorhees, Crop Insurance Specialist for 1st Farm Credit Services – Morton, worked with the author on this project and has been primarily responsible for the conduct of the survey and the building of the database of responses. He is a graduate student in the Agribusiness program at Illinois State University and his assistance was invaluable.
